MLBtv skips, stutters, unsyncs video

MLBtv skips almost immediately as i begin watching a game (i watch SNLA HD, for the Dodgers). the stream jumps backwards about 5-10 seconds, with the audio going back even further. as the broadcast continues, the audio trails the video by at least 5 seconds.

i've tried everything, including restarting Apple tv. when i use Airplay to stream the same broadcast from my iPad, it works fine.

no other app does this. Netflix streams fine. and this has been going on since spring training.
